Title: Production for channel made of boron-containing stainless steel
Inventor: YOSHIMURA KEISUKE
IPC: B23K10/02
Filed: 1985-05-13
Abstract: PURPOSE:To increase the performance in absorbing a neutron and the dimensional accuracy by arranging in rectangular shape the boron-containing stainless steel thin sheet and by subjecting the butt part thereof to plasma welding with a nonfiller. CONSTITUTION:The thin sheet 1 of a boron-containing stainless sheet is arranged at four sides by using a jig and assembled in the rectangular shape of a long size. In this case, on the butt part at right angles of adjacent thin sheets 1, 1 an excess metal part 1a' is formed with the slight overlapping of the one part of the thin plate 1a on the other part of the thin plate 1b. An integral rectangular channel 3 is then formed by combining this butt place 2 with the plasma welding of the excess metal part 1a' by the nonfiller. The boron component of the welding zone is not virtually reduced due to the butt place 2 being subjected to the nonfiller welding. The neutron absorbing performance is therefore increased. The dimensional accuracy of a channel 3 is further increased owing to the employment of the plasma arc welding method.

Title: Electrophotographic copying machine
Inventor: TSUKIJI TOSHIKAZU
IPC: G03G15/00
Filed: 1988-04-27
Abstract: PURPOSE:To prevent the surface of a photosensitive body from being contaminated with corona products by partial toner images by forming the partial toner images at the parts of the surface of the photosensitive body facing an electrostatic charger and a transfer device after copying operation is finished and then stopping the photosensitive body. CONSTITUTION:The photosensitive body 10 is further rotated after the end of the copying operation and the surface of the photosensitive body 10 is charged electrostatically by the electrostatic charger 11; and an image lamp 13 is put in operation twice to set the potential of the surface of the photosensitive body 10 to zero except at two positions 10a and 10b. Then partial latent images formed at the two positions 10a and 10b are developed by a developing machine 14 to obtain the partial toner images 201 and 202, the photosensitive body 10 is further rotated to put the toner image 201 opposite the electrostatic charger 11, and the photosensitive body 10 is stopped where the toner image 202 faces the transfer device 15. Consequently, corona products remaining nearby the electrostatic charger 11, transfer device 15, and a peeling device 16 do not contact the surface of the photosensitive body 10 directly even when the photosensitive body stops, so copy defects such as white absence and an image run due to surface contamination are eliminated.

Abstract: PURPOSE:A rubber compound that is made by adding a nonreinforcing inorganic filler and asphaltene to an elastomer mainly composed of halogenated butyl rubber, thus showing remarkably improved vulcanizing adhesion as well as tackiness, air-trapping, roll-releasability and other processing properties. CONSTITUTION:The compound comprises 100pts.wt. of an elastomer, which contains 50-100pts.wt. of halogenated butyl rubber in 100pts.wt. of the elastomer, 5-30pts.wt., preferably 10-20pts.wt. of nonreinforcing filler such as silicic acid, aluminum silicate, calcium sulfate and 5-30pts.wt., preferably 10-20pts.wt. of asphaltene such as straight asphaltene or blown asphaltene. During mixing above 130 deg.C, asphaltene bearing functional groups adheres to the surface of the filler through secondary bondings to form a high-dimensional structure between them. Thus, the surface of resultant compound is activated due to its higher molecular weight, wider molecular weight distribution, higher surface activity and higher dimensional structure of functional groups than only asphaltene.

Filed: 1988-04-26
Abstract: PURPOSE:To make cores forming a magnetic path thicker in thickness so as to improve the magnetic efficiency of the cores by making the thickness at the front gap of a magnetic body between a recording and reproducing gap and erasing gap thicker than that at the rear gap. CONSTITUTION:A front gap 3 for recording and reproduction and rear gap 9 for recording and reproduction are formed of cores 1 and 2 and front gaps 6 for erasure and rear gaps 10 for erasure are formed of cores 4 and 5. Then the cores 2 and 5 are joined with each other and recording, reproduction, and erasure are performed on a recording medium by means of the front gap 3 for recording and reproduction and the gap 6 for erasure. The interval T between the front gap 3 for recording and reproduction and the gaps 6 for erasure is set in such a way that the thicknesses of the rear gap sections of the cores 2 and 5 are made larger than those of the front gap sections of the cores 2 and 5. Since the thicknesses of the cores 2 and 5 at the rear gap section are increased without changing the interval T at the front gap section, the cores forming the magnetic path is made thicker in thickness and the magnetic efficiency of the cores can be improved.

Title: Striking tool
Inventor: TANAKA KAZUMOTO
IPC: B25D9/26
Filed: 1988-04-26
Abstract: PURPOSE:To prevent dust from being deposited between both air chambers to prevents a reduction in a striking force adjusting function of a striking tool by providing a volume varying means for varying the volume of a second air chamber while a relative position between a striking member, a piston member and the second air chamber formed in the striking tool body so as to be connected to a first air chamber is maintained. CONSTITUTION:A striking force is adjusted by adjusting the volume of a second air chamber 8 by means of a volume varying means (adjusting bolt) 9, adjusting the sum of the volume of a first air chamber formed between a striker 3 and a piston member 6 and the volume of the second air chamber 8, and adjusting the amount of advance and retract of the striker 3 with respect to a preset amount of advance and retract of the piston member 6. In this instance, since the second air chamber 8 is connected to the atmosphere only through the first air chamber 5 without being directly connected to the surrounding atmosphere, dust floating in the surrounding atmosphere does not penetrate into between both air chambers 5, 8, thereby being not deposited. A passage between the first and second air chambers 5, 8 is, as a result, no blocked by dust, and a reduction in the cross-sectional area of the passage can be prevented for many hours.

Title: Power amplifier circuit
Inventor: HIKITA JUNICHI
IPC: H03F1/56
Filed: 1986-05-06
Abstract: PURPOSE:To prevent the parasitic oscillation of an amplifier means by providing an impedance element between output sections of the 1st and 2nd amplifier means so as to omit a capacitor compensating the high frequency characteristic. CONSTITUTION:A potential across an impedance element 24 placed between the 1st and 2nd amplifier means (power amplifiers 20a, 20b) is set to a common DC output voltage VDC, then a DC current flowing to the impedance element 24 is prevented to prevent the power loss. Since the impedance element 24 acts like an imaginary ground point to the output of the 1st and 2nd amplifier means (power amplifiers 20a, 20b), the impedance element 24 has the same function as the capacitor even when the capacitor is omitted. Thus, the parasitic oscillation of the 1st and 2nd amplifier means (power amplifiers 20a, 20b) is prevented.
